With OneDrive on your phone or tablet, your files are secure and accessible from anywhere, on all your devices.
Download the OneDrive app from the Apple App Store.
Sign in with the work or school account you use for OneDrive to see and share your files stored in OneDrive.
To add another account, like your personal OneDrive account, tap the Accounts and Settings icon and then tap Add account.
If you have the Office mobile apps, like Word, Excel, or PowerPoint, you can also open, view, and edit your OneDrive files from there.
